Keep 40 GbE links direct, predictable, and easy to manage with this AddOn Networks compatible 40GBASE-CU DAC cable. The QSFP+ copper design is built for short-reach interconnects where performance, simplicity, and cost control matter more than optical flexibility. In dense switching environments, every port and every inch of rack space counts. A direct attach cable removes the need for separate transceivers and fiber patching, helping reduce component count while maintaining the throughput expected from 40 Gigabit Ethernet infrastructure. That makes it a strong fit for top-of-rack switching, server uplinks, and storage adjacency where short runs dominate. TAA compliance adds procurement value for organizations that need sourcing alignment without compromising on technical fit. For teams standardizing high-speed cabling across enterprise or public sector environments, this cable supports a cleaner bill of materials and a more controlled deployment model. It is the kind of interconnect that earns its place by being simple, fast, and appropriate for the job.
